4: Geothermal Energy | Geothermal energy is heat from within the Earth. Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth. | Geothermal energy is generated in the Earth's core. The temperatures even hotter than the sun's surface . We always use it for hot water, cooking and heating.

6: Geothermal Energy | Some applications of geothermal energy use the Earth's temperatures near the surface, while others require drilling miles into the Earth. There are three main uses of geothermal energy: -Direct use and district heating systems use hot water from springs or reservoirs near the surface. Electricity generation power plants require water or steam at very high temperature (300 to 700F). -Geothermal power plants are generally built where geothermal reservoirs are located within a mile or two of the surface. -Geothermal heat pumps use stable ground or water temperatures near the Earth's surface to control building temperatures above ground.

8: Geothermal Energy | There is almost no negative impact on the environment if we use it directly or use heating applications. So geothermal energe is useful and a great way to protect environment! And geothermal power is highly scalable: from a rural village to an entire city. There are a lot of place can find geothermal power! Is that cool?

10: Nuclear Energy | Nuclear power is energy which is produced with the use of a controlled nuclear reaction. Many nations use nuclear power plants to generate electricity for both civilian and military use. | Some people favor an expansion of nuclear power plants because this form of energy is considered cleaner than fossil fuels such as coal, although nuclear power comes with a number of problems which must be addressed, including the safe disposal of radioactive waste products

12: Nuclear Energy | ADVANTAGES | - Nuclear power costs about the same as coal, so it's not expensive to make. - Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. - Produces huge amounts of energy from small amounts of fuel. - Produces small amounts of waste. - Nuclear power is reliable.

14: Nuclear Energy | DISADVANTAGES | -Although not much waste is produced, it is very, very dangerous. -It must be sealed up and buried for many thousands of years to allow the radioactivity to die away. -Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster. -People are increasingly concerned about this because nuclear power is growing very fast.

16: Nuclear Energy | FUTURE | Today, nuclear energy supplies 7.5% of the total global energy consumption corresponding to about 17% of the global (20% of the U.S.) electricity consumption. | Some 575 nuclear power plants have been built, including 125 in the United States and an average availability for nuclear power plants of 73% (85%-90% in the United States). | However the future use of nuclear power is uncertain because it is very dangerous.

18: Nuclear Energy | WOW | A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. | In the history of warfare, only two nuclear weapons have been detonated offensively, both near the end of World War II. | Since the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over two thousand occasions for testing purposes and demonstration purposes.

20: Wind Energy | Wind energy is from moving air. It’s caused by heating of Earth’s surface by the sun. So the wind energy is renewable resource and it’s a clean source for environment. Wind energy has fewer environmental impacts than using many other resources. But there is still a problem of what to do when there’s no wind blowing, at this time, other power plant must work for electricity | Operating a wind power plant is not as simple as just building a windmill in a windy place. Wind plant owners must carefully plan where to locate their machines. It is important to consider how fast and how much the wind blows at the site

22: Wind Energy | One of the greatest advantages of Wind Energy is that it is ample. Secondly, wind energy is renewable. Some other advantages of Wind Energy are that it is widely distributed, cheap, and also reducing toxic gas emissions. Wind Energy is also advantageous over traditional methods of creating energy, in the sense that it is getting cheaper and cheaper to produce wind energy. Wind Energy may soon be the cheapest way to produce energy on a large scale. | Advantages | One other advantage of wind energy that it is readily available around the globe, and therefore there would be no need of dependence for energy for any country. Wind energy may be the answer to the globe's question of energy in the face of the rising petroleum and gas prices.

24: Wind Energy | Though the costs of creating wind energy is going down, even today a large number of turbines have to be built to generate a proper amount of wind energy. Though wind power is non-polluting, the turbines may create a lot of noise, which indirectly contributes to noise pollution. | Disadvantages | Wind can never be predicted.Even the most advanced machinery may come out a cropper while predicting weather and wind conditions. Since wind energy will require knowledge of the weather and wind conditions on long term basis, it may be a bit impractical. Therefore, in areas where a large amount of wind energy is needed, one cannot depend completely on wind. Many potential wind farms, places where wind energy can be produced on a large scale, are far away from places for which wind energy is best suited

26: Wind Energy | The Greenpower Utility System (GALE) line of vertical axis wind turbines from Diamond Wind Solutions not only offers buyers a choice of custom colors, it suggests a number of different graphics packages including the American flag and camouflage though we’re not sure the bats & birds would appreciate the latter. Then again, vertical axis wind turbines are usually compact in size and mounted close to the ground. | WOW

28: Solar Energy | Solar power is the conversion of sunlight into electricity, either directly using photovoltaics,or indirectly using concentrated solar power. CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam

30: Solar Energy | PV converts light into electric current using the photoelectric effect. Solar energy is one of the most resourceful sources of energy for the future. One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times that total energy used by man. However, about 1/3 of this energy is either absorbed by the outer atmosphere or reflected back into space.

32: Solar Energy | Solar energy is presently being used on a smaller scale in furnaces for homes and to heat up swimming pools. On a larger scale use, solar energy could be used to run cars, power plants, and space ships.

34: Hydro-Electric Energy | Hydrogen is a colorless, odorless gas that accounts for 75 percent of entire universes mass. Stars like the sun are made primarily of hydrogen. In the sun's core, hydrogen atoms combine to form helium atoms This process — called fusion — gives off radiant energy | Hydrogen gas is found on Earth only in combination with other elements such as oxygen, carbon and nitrogen. To use hydrogen, it must be separated from these other elements.

36: Hydro-Electric Energy | - Hydrogen is an alternative fuel high in energy. - Safety. For example, Hydrogen compared to gasoline in an explosion is safer. - Efficiency: Hydrogen is more efficient than gasoline and gas. - The use of hydrogen technology will also reduce the number of green house emissions in our atmosphere a machine that burns pure hydrogen produces almost zero pollution | ADVANTAGES

38: Hydro-Electric Energy | - Hydrogen does not occur naturally on Earth and thus is not an energy source. - It takes a great deal of energy to extract Hydrogen from water. - Storage: Storage is currently a problem with hydrogen technology in transportation. The hydrogen fuel must be heavily compressed to store enough to be suitable. | DISADVANTAGES

40: Hydro-Electric Energy | FUTURE | Hydrogen fuel cells make electricity. They are very efficient. Large fuel cells can provide electricity in remote places with no power lines. | Portable fuel cells are being sold to provide longer power for laptop computers, cell phones, and military applications. | Because of the high cost to build fuel cells, large hydrogen power plants won't be built for a while. However, fuel cells can will being use in some places as a source of emergency power, from hospitals to wilderness locations.

42: Hydro-Electric Energy | WOW | Many companies are working to develop technologies that might efficiently exploit the potential of hydrogen energy for mobile uses. The attraction of using hydrogen as an energy currency is that, if hydrogen is prepared without using fossil fuel inputs, vehicle propulsion would not contribute to carbon dioxide emissions | A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power. The term may refer to a personal transportation vehicle, such as an automobile, or any other vehicle that uses hydrogen in a similar fashion, such as an aircraft.

44: Biomass Energy | Biomass is made from plants and animals (microorganisms), it is organic material. | Biomass energy is derived from five distinct energy sources: garbage, wood, waste, landfill gases, and alcohol fuels. The wood energy can product fro making paper.

46: Biomass Energy | Waste energy is the second-largest source of biomass energy. The main contributors of waste energy are municipal solid waste (MSW), manufacturing waste, and landfill gas. How biomass works is very simple. The waste wood, tree branches and other scraps are gathered together in big trucks. The trucks bring the waste from factories and from farms to a biomass power plant. Here the biomass is dumped into huge hoppers. This is then fed into a furnace where it is burned. The heat is used to boil water in the boiler, and the energy in the steam is used to turn turbines and generators.

48: Biomass Energy | Using biomass can help reduce global warming compared to a fossil fuel-powered plant. The use of biomass can be environmentally friendly because the biomass is reduced, recycled and then reused. It is also a renewable resource because plants to make biomass can be grown over and over. And it is nature, clean, almost no negative impact on environment but burn it within no protection.

50: Biomass Energy | - The use of biomass energy has the potential to greatly reduce greenhouse gas emissions. Burning biomass releases about the same amount of carbon dioxide as burning fossil fuels. - The use of biomass can reduce dependence on foreign oil because biofuels are the only renewable liquid transportation fuels available. - In the near future—and with NREL-developed technology—agricultural residues such as corn stover (the stalks, leaves, and husks of the plant) and wheat straw will also be used. Long-term plans include growing and using dedicated energy crops, such as fast-growing trees and grasses, and algae. These feedstocks can grow sustainably on land that will not support intensive food crops.
